Description
Technical Field
The utility model relates to a cable duct protection device technical field specifically is a compound tub of mouth of pipe shutoff of steel plastic blocks up.
Background
With the acceleration of the modernization process of the country, the urbanization construction of various regions changes day by day, the rapid development of a plurality of cities needs more and more power supply facilities, the underground power supply grid develops rapidly, and the cable duct bank facilities buried underground develop rapidly in recent years so as to be used for the laying operation of city power supply cable lines.
After the urban underground cable calandria is laid, cables are already threaded in some calandrias, and some calandrias are left vacant for standby application, so that the requirement for increasing cable lines in the future is met. The spare cable calandria is arranged among a plurality of underground working wells, no cable passes through the spare calandria, and no object is blocked at pipe orifices at two ends of the calandria, after a period of time, underground water or rainwater in the working wells flows, or small animals such as water rats, snakes and the like flow in the calandria and nest, or other sundries, dirt and sludge in water flow enter the calandria to cause the blockage of the calandria, and particularly hard small stones are left in the calandria to damage the outside of the cable during the future cable laying.
The existing pipe orifice sealing plug has poor sealing performance and high manufacturing and using cost.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
In order to solve the above problems in the prior art, the utility model provides a compound pipe mouth of pipe shutoff of steel plastic blocks up solves current mouth of pipe shutoff leakproofness relatively poor, makes simultaneously and the higher problem of use cost.
(II) technical scheme
In order to achieve the above object, the utility model discloses a main technical scheme include:
the utility model provides a compound pipe mouth of pipe shutoff of steel-plastic is blockked up, includes the cock body, the internal intermediate position of cock is provided with the screw hole, screw hole inner chamber threaded connection has the nut, nut left side one end fixedly connected with pull rod, pull rod left side one end is provided with the stopper, the pull rod outer wall just is located and is provided with the sealing ball between cock body and the limiting plate, cock body right side outer wall position still is provided with the rotation handle.
Preferably, the outer wall of the nut is provided with an external thread.
Preferably, the sealing ball is made of rubber.
Preferably, the nut is a hexagon socket nut.
(III) advantageous effects
The utility model provides a steel-plastic composite pipe mouth of pipe shutoff stopper. The method has the following beneficial effects:
(1) the stopper body is plugged into the pipe orifice, then the rotation handle is rotated and the stopper body is fixed, then the nut is rotated, the rotation of nut can drive the pull rod and move, then the cooperation stopper extrudees the ball sealer, the ball sealer extrusion process takes place can seal the pipe orifice, seals up with traditional sealed pad mode and compares, and this kind of sealed effect is better.
(2) The nut is an inner hexagon nut, so that the nut can be prevented from being disassembled to a certain extent.
Drawings
Fig. 1 is a front sectional view of the present invention;
fig. 2 is a right side view of the present invention.
In the figure: 1. a plug body; 2. a threaded hole; 3. a nut; 4. a pull rod; 5. a limiting block; 6. a sealing ball; 7. the handle is rotated.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-2, the utility model provides a technical solution: the utility model provides a compound pipe mouth of pipe shutoff of steel-plastic is blockked up, includes cock body 1, 1 inside intermediate position of cock body is provided with screw hole 2, 2 inner chamber threaded connection of screw hole have nut 3, 3 left side one end fixedly connected with pull rod 4 of nut, 4 left side one ends of pull rod are provided with stopper 5, 4 outer walls of pull rod just are located the position between cock body 1 and the limiting plate and are provided with sealing ball 6, 1 right side outer wall position of cock body still is provided with rotation handle 7. And the outer wall of the nut 3 is provided with an external thread. The sealing ball 6 is made of rubber. The nut 3 is a hexagon socket nut 3. During the use, fill in the mouth of pipe to cock body 1, then rotate and rotate handle 7 and fix cock body 1, use hexagon socket head wrench swivel nut 3, nut 3 and 2 meshes of screw hole, then drive pull rod 4 and remove, pull rod 4 removes and makes the stopper 5 and the distance between the cock body 1 diminish extrusion ball sealer 6, ball sealer 6 extrusion process takes place deformation, ball sealer 6 after the deformation can seal the mouth of pipe, when needing to dismantle, use hexagon socket head wrench counter-rotation nut 3, make ball sealer 6 reconversion. Then the handle 7 is rotated to be disassembled.
The working principle is as follows: during the use, fill in the mouth of pipe to cock body 1, then rotate and rotate handle 7 and fix cock body 1, use hexagon socket head wrench swivel nut 3, nut 3 and 2 meshes of screw hole, then drive pull rod 4 and remove, pull rod 4 removes and makes the stopper 5 and the distance between the cock body 1 diminish extrusion ball sealer 6, ball sealer 6 extrusion process takes place deformation, ball sealer 6 after the deformation can seal the mouth of pipe, when needing to dismantle, use hexagon socket head wrench counter-rotation nut 3, make ball sealer 6 reconversion. Then the handle 7 is rotated to be disassembled.
